which is guided by the bushing, 8. This To whom it may concern:

Be it known that I, EDWARD S. HALSEY,

- a citizen of the United States. residing at Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Temperature Regulat-ing Valve Mechanisms, described and set forth'by the following specifications-and claims.

This invention relates especially to the thermostatic control of steam flow or sup- -ply valves'in the-development of which I have employed the'p'rinciple of operation disclosed by Patent Number, 1129433 of Julian Stratton. issued Feb. 23rd, 1915, in which a volatile liquid-i dripped into a hot volatilizing chamberfrom whence it distils out into a cold chamber and from which its returnto the hotchamber is controlled by external thermostatic means.

The objects of my invention are to contrive means of incorporating this principle into a steam throttling valve so that by simpl and efiicient means the main throttle valve will be internally actuated by the powerful expansion of the volatile liquid under the sensitive control of a primary external thermostat, of relatively small and sensitive proportion.

Referring to the accompanying drawings which illustrate my invention similar reference characters refer to similar parts throughout the several views in which Figure 1 is a side elevation in cross section of an angle steam valve with thermostatic attachments. Fig. 2 is a horizontal cross- Section through 22 of same. While Fig. 3 is a side elevation in cross section of a similar valve tothat shown in Fig. 1.

Referring to Fig. 1, the angle body 1, incloses an elastic metal expansion chamber, 2, which is attached to a hollow stud of bonnet, 12, through which it communicates to the condensing chamber, 3, by means of the insulating tubular neck, 5, and the crescent channel, 9. In this case the primary expansion from vaporization of the dripping liquid occurs where the drops fall on the hot chamber walls in the passage-way to the diaphragm section of the expansion chamber or space. The bottom of this condensin chamber which is spherical in form constatutes a catch basin for the condensing liquid 4. At the lowest central point is a small opening, normally closed by the weighted needle valve, 6, the upper end of needle valve may be raised and opened bya very slight raising pressure on the angle lever, 7, which is fulcrumed-in the center of a small thin flexible metaldiaphragni, 17. which is soldered or otherwise secured over an aperture-in the sideof the condensing chamber. This lever -o'r, valve stem is clamped firmly on either side of the diaphragm by a pair of crown-faced nuts, 16,

which permit it to rock practically free of friction and with hardly an appreciable distortion of the diaphragm with a very minute application of energy. In this figure the thermostatic source of energy is indicated as being supplied by the bi-metal bar, 13, an-

chored at the lower end and pressing on the valve lever through the medium of an adjusting screw at the top end. This illustrates symbolically the application of any known type of primary thermostat which may be used in carrying out this invention.

In Fig. 3, the valve lever, 7, instead of being L shaped is left straight and its outer end is shown as being connectedwith a .distant actuating thermostat (which may be of any type desired) through the medium of the tensioned ligament, 15, passing over pulley, 18, or otherwise.

In this figure I have shown an accordion bellows expansion chamber instead of the double diaphragm expansion chamber shown in the first figure. To the bottom of the bellows is fixed a cone, 19, constituting a throttle by closing, and seating on, the opposing port. I have also shown an additional communicating tube, 5', for the hot vapor o pass up through to the condensing chamber in addition to the central thermal insulating tube, 5, through which the liquid drips into the hot chamber.

In order to make the whole device compact and of short stature and have the condenser rapid and efiicient in action I out down the "conducted heat between the hot valve body and the air cooled condensing chamber to a very large degree by employing connecting tubes, 5, of thin cross-section and made from thermal insulating metals, or in other words having relatively high heat resistance as compared to that of the brass of which the valves are made, for instance, iron which has over twice the resistance of brass. I prefer however to use an alloy of nickel steel high in nickel which has many times the resistance of iron or ill) brass, or alloys of nickel and copper, such as Monel, or conglomerate mixtures of iron, nickel, copper, etc., such as German silver, nichrome, etc.

While I have only shown two modifications of my invention, it is obvious that it may be made up and applied in numerous other forms and applications. For instance, instead of the rock lever and dia phragm, pressure diaphragms may be employed and instead of the mechanical application of the power from the primary thermostat, it may be communicated through fluid pressure tubes, etc, etc,

ll claim:

1. In a radiator supply valve, a body housing a throttle; a flexible expanding chamber in said body connected to said throttle; an intercommunicating air cooled condensing chamber above said expanding chamber; a catch basip for said condensing chamber; a drip valve between said basin and said lower expanding chamber; an external primary actuating; thermostat in working engagement with said drip valve; and a relatively slender thermal insulating neck between said air cooled chamber and the heated body of said valve.

\ 2. ln a steam supply valve a body housing a throttle; a flexible expanding chamber in said body connected to said throttle; an externally cool condensing chamber above said naaaaei expanding chamber; a catch basin for said condensing chamber; a drip valve between said basin and lower expanding chamber; an external primary actuating thermostat in working engagement with said drip valve; and a thermal insulating neck between said externally cooled chamber and the heated body of said valve consisting of a relatively poor conducting metal alloy.

3. In a thermostatic steam throttling valve a throttling device; a housing body therefor; a flexibly walled, normally dry, vaporizing, throttle actuating expansion chamber incorporated in and heated by contact with said body and steam; a cooled, intercommunicating condensing chamber of higher elevation than the vaporizing portion of said expansion chamber; a liquid catch basin to said condensing'chamber; a drip valve from said basin controlling the flow of said liquid to said vaporizing expansion chamber; and a primary external thermostatic controlling device in working engagement with-said drip valve.

Having described my invention it hereunto set my hand inthe presence of two witnesses this 12th day of September, 1916.
